Abstract
Systems and methods for treating a metal or metalloid ion-contaminated liquid are provided. The method may include (i) feeding the metal or metalloid ion-contaminated liquid into a bioelectrochemical reactor containing a bacteria selected by the cathode to produce extracellular metal or metalloid nanoparticles; and (ii) operating the bioelectrochemical reactor anaerobically to reduce the metal or metalloid ions in the metal or metalloid ion-contaminated liquid to extracellular metal or metalloid nanoparticles. The method may further include separating the metal or metalloid nanoparticles from the bacteria with no energy input. A bioelectrochemical reactor system for production of extracellular metal and metalloid nanoparticles may include a bioelectrochemical reactor, a separation device, and a tangential flow filtration unit.
